Cisco and Juniper routers to communicate

sendalot

I just got myself a Juniper Security Gateway (JUNOS Router) on top of my existing Cisco network.
Has anyone done a inter-vendor routing?

I want to implement OSPF (since both vendors support it) to have them talk to each other.

If I want Juniper's outside interface plugged into a Cisco switch that connects to a Cisco IOS router, do I simply give a static ip on that interface Juniper connects to?

Also, I want as simple areas a possible. Shall Juniper's inside be area 1 and Cisco/Juniper outside area be 0 and Cisco's inside by area 2?

So we are looking at ISP <-> CiscoRouter <-> CiscoSwitch <-> Juniper Router, where <-> is an Ethernet cable.

Thanks.

Yes just give the interface and ip address, if you want it as simple as possible why not make it all area 0. I hope this is a testlab, not a production config . The one thing you will have to be careful on is the ip mtu, i'm not sure whether juniper include the layer 2 header or not. Ospf needs mtu to match on both sides, just know their could be a 14 byte discrepency, i.e. you might have to make mtu 1514 on junos and 1500 on cisco.
